I was wondering if anyone has been having this problem. I have the mirror that shows the direction you are traveling and the outside temperature. Now, instead of it saying the temperature, it just says "OC" underneath the direction. Anyone have a solution? Thanks.

Yes.










































Have you used the handy search feature? You would find that this is likely caused by one of 2 things. First, the ambient air temperature sensor may have gone bad. Secondly, wiring from the sensor to the mirror may have gone bad. Either way, you would get OC (which stands for OPEN CIRCUIT).

OC = Open Circuit..

IE. Check your wiring/connections.

When my sensor was going bad, it would sometimes say "OC" and sometimes show the temp. I replaced the sensor and its been fine ever since.

"OC" Rear view mirror

Hi to all of you. I am new to this site so I am phishing around to get some answers. I hope I am in the right place.
I have a 2003 Trailbalzer that has a "OC" on the rearview mirror which I have found means open circuit.
I have looked at the pictures on this site and this one is not loscated where it is shown. Has any one else found it in another area? If so maybe you could describe in detail or post a picture?
I would appreciate any information any one has.:tiphat

Ok! I went back a looked where the pictures described it and low and behold it was right there. I think I was working to hard at this.
My wife had it into the local garage for this 6 times in the past 3 years asking to fix it and they didn't. Now she thinks I am a hero.

OC Mirror

Yes you are correct. I almost had the whole wiring harness out this morning looking for it. I just went out lifted the hood and it was right there.
